Actuating element (10) for a central door-locking system of motor-vehicle doors, in which an electric motor (11) directly drives a threaded spindle (12). The threaded spindle (12) is equipped with a small pitch angle (19). On the threaded spindle (12) is an axially displaceable spindle nut (13) which is guided fixedly in terms of rotation in guide grooves (14). A blocking part (21) can be brought into the unlocking and the locking position as a result of the rotation of the threaded spindle (12). <IMAGE>
